Patented July 15, 1930 PATENT OFFICE WILLIAM D. CROWELL, OF ST. LOUIS, MISSQURI VENTILATING MEANS FOR VEHICLEiBGDIES 'Application led December 31, 1928. Serial No. 329,405.

v previously referred to consists of a windowor other kind of movable closure for an opening in the side Wall of a vehicle body, constructed so that when it is in a partiall open condition, an exhaust opening will be fdrmed in said side wall through which air, gasesA and the likewill be withdrawn from the interior of the body by the rush of air past said exhaust opening, Without liability of airblowing into the body through said exhaust opening. My present invention consists of a side door for a vehicle body of the closed type, provided with a window that ,is composed of a plurality of vertically-divided sections, one of which is capable of being moved relatively to the door, so as to form a Ventilating opening or exhaust opening of the kind previously mentioned. Preferably,'the section of the window that is adapted -to be adjustedor moved so as to produce the exhaust opening or Ventilating opening, is mounted in such a Way that it can be moved downwardly into a pocket in the door and arranged in various positions so as to vary the size of said opening.

Figure l of the drawings is a side elevational view of a portion of an automobile body equipped with a Ventilating device constructed in accordance with my present invention.

Figure 2 is a vertical longitudinal sectional View of the body, looking outwardly to- Wards the side wall; and

Figure 3 is a horizontal sectional taken on the line 3,-3 of Figure 1.

View,

Referring to the drawings which illustrate the preferred form of my invention, A designates a vehicle body, for example, an automobile body of the closed t pe, Bdesignates a door in the side wall o said body and Bl designates a window frame constituting the upper half of said door, the lower 'half of said door being constructed so as to serve as a window pocket. The Window surrounded by the -frame B is composed of a plurality of vertically-divided sections, at least one of which is capable of beingmoved relatively to the door, so as to form a Ventilating opening or exhaust opening through which air, gases, smoke and the like will be Withdrawn from the interior of the vehicle body by the air that rushes rearwardly over the side wall when the Vehicle is traveling forwardly.

In the form ofl my invention illustrated in i lsections C and C are lowered, and if it is desired to close the window but at the same time ventilate the body, the window section C is moved upwardly into its full closed position, as shown in Figures 1 an 2, and the window `section vC is arranged in a artially open position, so as to form a ventilating slot or exhaust opening between the top edge of said section C and the top member of the window frame B.

In a vehicle body of the construction above described the interior of the bodyfwill be maintained in a properly vented condition when the vehicle is in motion, if the window sections C and Care adjusted in the posi-y tion vshown in Figures 1 and 2, due to the fact that the currents of air,4 represented by the arrow sin Figure 3, that strike against the front side of the wind shield 1 of the body and then escape laterally at the ends of said wind shield, will create a suction in flowing rearwardly across the exhaust openings m in the doors B that is of sullicient intensity to cause foul air, gases, smoke and the like to be withdrawn from the interior of the body through said exhaust openings as indicated by the arrows 'w in Figure 3. There is a natural tendency for the air currents to How inwardly towards the side walls of the body, but such inwardlyflowing air currents are shunted oli1 and prevented from entering the body of the window sections Cf in the doors B, which, at 4such times, are in their closed or fully raised position, the window sections C being made of such width that the rearwardly-flowing air currents will jump the exhaust openings before flowing inwardly towards the Side walls, as clearly indicated by the arrows in Figure 3. lVhile Figure 3 shows the doors B in the opposite side walls of the body, equipped with windows of the kind previously described, I wish it to be understood that it is immaterial, so far as my invention is concerned, whether only one or both of said doors are provided with such windows.

In a vehicle body equipped with a conventional one-piece window that extends across the entire width of the window opening, the slot that is produced between the top edge of the window and the top member of the Window frame when the window is in a partially open condition, is so longr that air will blow into the vehicle through the rear end portion of said slot when the vehicle is traveling forwardly, due to the natural tendency of the air currents to flow inwardly towards the side wall shortly after said air currents have passed the corner at the junction of the wind shield at the front end of the side wall. In my improved construction this cannot occur when the window in the door B is adjusted so as to ventilate the body, due, of course, to the fact that said window comprises one portion, to wit, the section C. that can be adjusted so as to form a relatively short ventilating slot or exhaust opening .7: at the top edge of said section, and a different portion,

to wit, the section C', that can bev adjusted so as to form in effect a solid portion of the side wall that is located at the rear end of .the slot Usually, each ofthe window sections C and C will be formed from a sheet of relatively thick glass, and said sections will be ar-Vv ranged in the same vertical plane or in substantially abutting relationship with their adjacent vertical edges, slidingly mounted in a guiding device 2 of substantially H shape in horizontal cross section whose flanges empreviously described, but usually it will be found that the vehicle can be kept properly ventilated, if only one door of the vehicle, preferably, one of the front doors, is provided With a. window comprising at least one vertically-adjustable section that can be moved into such a position as to form a ventilating slot or opening af of the kind previously mentioned.

Having thuzrl described my invention, what I claim as new and desire to secure by Letters i Patent is:

1. A vehicle body having a side door provided with a window composed of a plurality of vertically-divided sections, each of which portion is constructed so as to form a window pocket, a window surrounded by said `frame and composed of a plurality of vertically-divided sections, each of which is capableof being moved vertically independently of and relatively to the other section y and a raising and lowering mechanism for the front section, by means of which said section can be lowered slightly into said pocket without disturbing the other section, so as to form an exhaust opening through which air, gases, smoke and the like will be withdrawn from the interior of the body by the rush of air rearwardl over Vthe side wall of the body when the vehicle is traveling forwardly.

3. A vehicle body having a side door provided with a window composed of a plurality of vertically-divided sections, each of which is capable of being moved vertically independently of and relatively to the other section, a pocket in said door, and a raising and lowering mechanism combined with each of said window sections, the front window section that is located nearest the front edge of the door being adapted to be moved downwardly into `said pocket into a partially open condition so as to form a Ventilating or exhaust opening when the other section is in its raised or closed position.

4. In a vehicle body of the closed type, the combination of a side wall, a door in sald side wall provided with a window composed of a plurality of vertically-divided sections arranged in the Same vertical plane and each being capable of being moved vertically independently of and relative to the other, a window pocket in said door, and means for ies.

enabling the front window section to be moved down-wardl into said pocket into a partially open con ition when the other section is closed, so as to produce -an exhaust opening of less width than the window throu h which air, gases and the like will be sucke out of the interior of the body by the A rush of air rearwardl past said exhaust opening when the vehic e is in motion. v 5. A side door for a vehicle body, having an upper portion constructed so as to serve as a window frame and a lower portion constructed so as to serve as a window pocket, a window in ysaid frame composed of a pluerality of vertically-divided sections that lie in the same vertical plane, a raising and lowering mechanism combined with each of said window sections whereby said sections may be lowered or raised independently of each other, into and out of said pocket, and a vertically-disposed guiding device on the door interposed between adjacent sections of' the window and provided with portions that lapI over said sections.
